Product Overview

The Solar Electric STKP-60-260 is a durable 260Wp polycrystalline solar panel built for reliable daily energy production. It uses a glass/glass design that improves protection against UV exposure, moisture, ammonia, and salt corrosion. This construction supports long service life and stable performance in demanding environments. The module is designed for residential and commercial solar installations where strong output, dependable warranties, and solid mechanical strength are important. With 60 cells, MC4 connectivity, and a compact 1673 x 991 x 5.4 mm format, it offers a practical balance of size and performance.

Key Benefits

Durable Glass/Glass Construction: The back glass design strengthens the module and improves resistance to harsh weather conditions.

Long-Term Warranty Support: It includes a 15-year product warranty and a 30-year performance warranty for lasting confidence.

Stable Power Delivery: The panel delivers 260Wp output with a power tolerance of 0 to +3%.

Reliable Outdoor Performance: It operates from -40°C to 85°C and is suited to variable climate conditions.

Easy System Integration: MC4 connectors and a 4 mm² cable cross-section simplify installation and compatibility.

How It Works

This solar panel converts sunlight into usable electricity through its polycrystalline photovoltaic cells. Incoming light creates direct current, which can then be used by solar equipment or routed through an inverter for AC power. The glass/glass build helps protect the cells while supporting long-term reliability. Its electrical ratings are designed to help installers size strings accurately and match the module with suitable system components. Because the panel is engineered for broad operating temperatures and consistent output, it works well in everyday rooftop and ground-mounted solar applications.

Photovoltaic Conversion: Sunlight strikes the polycrystalline cells and generates electrical current. The module then produces DC power for the solar system.

Glass/Glass Protection: Two layers of glass encase the cells and improve resistance to moisture and corrosion. This structure supports durability in tough environments.

System Matching: The module’s voltage, current, and fuse ratings help installers connect it safely. It is built for straightforward use in compatible solar arrays.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Jacob B

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!
